Description

Technical Field

[0001] This application relates to the field of environmental control technology, specifically to an airflow regulator. Background Technology

[0002] In existing ventilation systems, the air volume regulation of internal and external circulation usually relies on two separate devices for control, which not only increases equipment costs and installation space, but also makes operation and control more cumbersome.

[0003] For example, in the air conditioning and ventilation systems of some buildings, an air volume regulator is usually installed inside the duct to adjust the air volume. However, traditional air volume regulators can only perform simple on / off operations or coarse adjustments to the air volume. These systems usually only have a single external circulation function and cannot flexibly switch between internal and external circulation modes according to indoor environmental conditions. Moreover, when encountering humid weather such as rain, the humid air introduced by the external circulation may damage the internal electrical components. When it is necessary to quickly adjust the indoor environment (such as temperature and humidity), traditional air volume regulation methods also cannot achieve precise and synchronous adjustment of the internal and external circulation air volume, which significantly affects the overall efficiency of the ventilation system. Utility Model Content

[0004] Therefore, this application provides an air volume regulator to solve the problem that existing ventilation systems use independent devices to control internal and external circulation separately, which leads to increased installation space and cumbersome operation.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An air volume regulator includes an air valve frame, which is installed on an air duct within a structure. The outer wall of the air duct has a through hole corresponding to the position of the air valve frame, and the through hole allows the air duct to communicate with the interior of the frame.

[0007] A valve leaf is provided on the inner side of the air valve frame. The valve leaf is rotatably connected to the inner side of the air valve frame via a rotating shaft. An electronic control module is provided on the outer side of the air valve frame. The output end of the electronic control module is connected to the rotating shaft.

[0008] Optionally, the valve blades include a plurality of valve blades arranged sequentially along the length of the valve frame, and each valve blade is connected to the others by a linkage mechanism.

[0009] Optionally, the multiple valve leaflets have different sizes.

[0010] Optionally, the dimensions of the plurality of valve blades increase sequentially along the length of the valve frame.

[0011] Optionally, the number of valve leaflets is 1 to 3.

[0012] Optionally, the electronic control module includes a motor and a controller, wherein the output terminal of the controller is connected to the input terminal of the motor, and the output terminal of the motor is connected to a rotating shaft.

[0013] Optionally, the outer periphery of the damper frame is provided with multiple fixing holes, so that the damper frame can be installed on the air duct by screws.

[0014] Optionally, a sensor is provided inside the structure, and the output terminal of the sensor is connected to the input terminal of the electronic control module.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. Based on further analysis and research of the problems in the prior art, this application provides an airflow regulator installed on the air duct within a structure. It includes a valve frame, with a valve blade disposed on the inner side of the valve frame. The valve blade is rotatably connected to the inner side of the valve frame via a rotating shaft. An electrical control module is disposed on the outer side of the valve frame. The electrical control module controls the operation of the rotating shaft and drives the valve blade to rotate, thereby regulating the airflow within the air duct. This application achieves airflow regulation through the rotation of the valve blade, thus realizing precise, synchronous regulation and reasonable distribution of internal and external circulation airflow. It has the advantages of compact structure, simplicity, and convenient installation, reducing equipment costs and installation space. Furthermore, it eliminates the need for frequent manual operation, reducing labor intensity and improving the overall performance of the ventilation system.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0036] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0037] One embodiment of this application is an airflow regulator 1 installed on the air duct 4 of a structure, specifically on the air duct 4 of the building 2 and the cabinet (such as control cabinet, distribution cabinet, SVG cabinet and other electrical cabinets), which can realize the internal circulation, external circulation or simultaneous internal and external circulation of airflow in the air duct 4, and is used for airflow exchange and heat dissipation.

[0038] See Figures 1-11 The air volume regulator 1 provided in this application includes a damper frame 11 installed on the air duct 4. The outer wall of the air duct 4 has a through hole corresponding to the position of the damper frame 11, and the through hole connects the air duct 4 to the inside of the frame.

[0039] A valve leaf 12 is provided on the inner side of the air valve frame 11. The valve leaf 12 is rotatably connected to the inner side of the air valve frame 11 via a rotating shaft 14. An electrical control module 13 is provided on the outer side of the air valve frame 11. The output end of the electrical control module 13 is connected to the rotating shaft 14.

[0040] Preferably, the valve blade 12 includes a plurality of valve blades 12 arranged sequentially along the length of the air valve frame 11, and each valve blade 12 is connected to each other by a linkage mechanism (not shown in the figure).

[0041] More preferably, the multiple valve blades 12 have different sizes.

[0042] More preferably, the dimensions of the plurality of valve blades 12 increase sequentially along the length of the air valve frame 11. Simultaneously, during installation, the dimensions of the plurality of valve blades 12 increase sequentially along the airflow direction of the air duct 4.

[0043] By dividing the valve blade 12 into multiple parts and connecting each valve blade 12 with a linkage mechanism, this design can achieve step-by-step blocking of wind force. Especially when the wind force is strong, the previous valve blade 12 blocks the wind force of the next valve blade 12. Through step-by-step attenuation and synergistic effect, it can effectively block the wind force, which not only improves the stability and reliability of the system, but also optimizes the wind force distribution, reduces airflow impact, adapts to different wind conditions, improves the operating efficiency of the system, and extends the service life of the valve blade 12.

[0044] Preferably, the number of valve blades 12 is 1-3. This embodiment provides two types of valve blades 12, referred to as the first valve blade 121 and the second valve blade 122, respectively, and the size of the first valve blade 121 is larger than the size of the second valve blade 122.

[0045] Preferably, the electronic control module 13 includes a motor and a controller, the output terminal of the controller is connected to the input terminal of the motor, and the output terminal of the motor is connected to the rotating shaft 14.

[0046] The controller controls the rotation of the motor, which drives one of the valve vanes 12 to rotate around the rotation axis 14. The rotation of the valve vane 12 is transmitted to the other valve vanes 12 through the linkage mechanism, thereby driving all valve vanes 12 to rotate synchronously and achieving coordinated control of the airflow in the air duct 4.

[0047] More preferably, a sensor is provided inside the structure, and the output end of the sensor is connected to the input end of the controller for electrically controlling the valve leaf 12, such as automatically controlling the valve leaf 12 to open or close according to environmental parameters, or controlling the opening or closing of the valve leaf 12 according to a remote command.

[0048] Preferably, the outer periphery of the damper frame 11 is provided with a plurality of fixing holes 111, so that the damper frame 11 is installed on the air duct 4 by screws.

[0049] The working principle of the above embodiments:

[0050] For example, a cabinet 3 is installed in building 2, and an air volume regulator 1 is installed on the air duct 4 connected to the cabinet 3 to control the air flow in the air duct 4 to meet the ventilation needs of different areas in building 2. When the electrical components in building 2 are working normally, they all need to dissipate heat. At this time, by controlling the opening and closing of the valve leaf 12 by the controller, different air volumes can be passed through the air duct 4, thereby achieving temperature control and simultaneous control of internal and external circulation.

[0051] When valve vane 12 is in the fully closed state, see Figures 6-8At this time, the valve blade 12 is parallel to the airflow direction of the air duct 4, the cross-sectional area of ​​the air duct 4 is the largest, all the air volume is discharged to the outside through the air duct 4, and fresh air from the outside is introduced into the building 2 through exchange with the outside air, thereby realizing temperature control and external circulation control in the building 2.

[0052] When valve leaf 12 is in the fully open state, see Figures 9-11 At this time, valve leaf 12 completely blocks air duct 4, and all air volume is discharged into the room through the through hole in the middle of air valve frame 11, thereby realizing temperature control and internal circulation control in building 2.

[0053] When the valve leaf 12 is in a semi-open state, the valve leaf 12 rotates at a certain angle and blocks the cross section of the air duct 4 to a certain extent. Part of the air volume is discharged to the outside through the air duct 4, and the other part is discharged to the room through the through hole in the middle of the air valve frame 11, thus realizing the temperature control in the building 2 and the simultaneous control of internal and external circulation.

[0054] In summary, this application has at least the following advantages:

[0055] 1. This air volume regulator is a fixed structure installed on the structure, and can be easily and quickly fixed on the structure. Through the electronic control module, it realizes the internal circulation, external circulation, or simultaneous internal and external circulation of airflow in the duct. The overall structure is compact and easy to install, reducing equipment costs and installation space. The intelligent control of the electronic control module makes the air volume adjustment more automated and intelligent, eliminating the need for frequent manual operation, reducing labor intensity, and improving the overall performance of the ventilation system.

[0056] 2. The electronic control module and sensor settings enable synchronous and precise adjustment of internal and external airflow, and can quickly adjust ventilation strategies according to changes in indoor and outdoor environmental parameters, thereby improving the efficiency of the ventilation system.

[0057] 3. The multi-stage valve design effectively blocks wind through progressive attenuation and synergistic effect, which not only improves the stability and reliability of the system, but also optimizes wind distribution, reduces airflow impact, improves the system's operating efficiency, and extends the service life of the valve.

[0058] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
